Unused, made by Hitoshi, high-grade one-touch soroban, boxwood beads, 23 digits, Tomoe This is a high-grade one-touch soroban from Tomoe. Excluding Mr. Itoga, the craftsman is probably one of the top two at Tomoe, using boxwood beads. As you know, boxwood bead soroban are relatively expensive. This item was found at my parents' house and is unused. Thank you for looking.
